This has already happened; most terrorist attacks these days occur at malls and schoolhouses.
Same memetic infection to disrupt and destroy, same domestic hysterics, same feedback cycle. So it goes until the next big meme shift for the dissatisfied comes along.
>Not to mention that TSA over and over again fails their undercover inspections.
Every (mid-2000s) attacker that managed to get through the incompetent security was defeated by the best security force available: passengers that know that allowing their plane to be hijacked or threatened by a bomb means certain death for everyone on board should they stay in their seats and permit it.
There have been a few cases where the pilot waited for the co-pilot to use the restroom, locked them out of the cockpit with the post-9/11 door, then intentionally crashed the plane.
All of these incidents were overseas. One was confirmed, and one or two more are suspected cases of pilot suicide.
When passengers have been able to intervene, they have defended their airplane 100% of the time.
When passengers have been prevented by regulatory means from defending themselves, they have failed to defend against a "trusted" figure turned attacker 100% of the time.
Sometimes the correct approach really is to do nothing.
As the other person commented: instances of pilot suicides like this occurred outside the US, not under FAA justification.
Also, why is it up to the airline to tell TSA whether I am enrolled in PreCheck or not? If it’s not on my boarding pass, I must not have PreCheck, huh? Department of Homeland Security isn’t really sure whether I have PreCheck or not.
Isn't that an improvement? You can't fly a security queue into a skyscraper or a crowded arena.
Not to mention that TSA over and over again fails their undercover inspections. In some cases 95% of weapons and explosives make it through TSA without any issues! Airport security literally is theater. At best it'll result in the terrorist attack being moved from the airplane to the security queue.
